It was initially thought she had perished in an accidental fire but a post-mortem showed that she had suffered fatal stab wounds and police believe a fire was started in her home in a bid to cover up any evidence.

Police believe that Jennifer knew her killer and trusted she was safe in their company in her house.

He said: “We are still looking for a light cream, bomber-style male’s jacket that we believe was discarded on the night of the murder.

“We are very anxious to find this jacket and we believe it could be lying in a back garden or similar close by. It could have been bundled up and thrown over a fence or wall, particularly between Hazel View and Poleglass.

“The public have been fantastic in the help and assistance they’ve given us and we are asking for their help again.

“Please look for this jacket on your property, please keep an eye out for it anywhere and everywhere you are.
